To aZZ whom it may concern: parallel with Fig. l in the line 3 3 of Fig. 2;

Be it known that I, EDGAR H. COTTRELL, a Fig. 4, a transverse section of the collecting citizen of the United States, and a resident of cylinder, transfer-cylinder, and folding-table; Stonington,-in the county of New London and Fig. 5, a side view, partly in section, of cam 5 State of Connecticut, have invented a new mechanism for opening the grippers of the 5 and useful Improvement in Machinery for collecting and transfer cylinders; Fig. 6, a Cutting and Folding Paper and other Fabside view of parts of the mechanisms for closrics, of which the following is aspecification. ing and opening the grippers; Fig. 7, a plan The cutting and folding machinery which of parts of the collecting and transfer cylinl0 constitutes this invention is intended as a ders and of the mechanism for operating 4 whole to be usedin connection with a pertheir grippers; Fig. 8, a front view of parts fecting printing-machine in which the printof the cam mechanism for operating the griping of pages sufficient to make a signature is pers of the two cylinders; Fig. 9, a side view performed on a continuous web before cutof the cam. and part of its connections for is ting the latter into sheets.

In the upper part lecting-cylinder for collecting the sheets one of this'framing are feed-rollersv B, which renpon another, and a second cylinder, which ceive the Web a and feed it to the cutter, may be termed a transfer-cylinder, for which is represented as consisting-of two rotaking collections of sheets from the collecttary cutter-carriers O and attached cuttinging-cylinder and piling one upon another a blades 0, the shafts b-of said carriers 0 runplurality of said collections ready for folding. ning in suitable bearings in the framing and The invention further consists in certain being geared together by gearsb.'

The invention is illustrated in the accom- At some distance below the collecting-cyl panying drawings, which represent cutting inder I) there is supported in the framing or and folding machinery for producing four stationary horizontal bars E the stationar;

,5 sixteen-page open-edged signatures from two slotted table E, upon which two collections 0 collections, each consisting of two sixteensheets made by the cylinderD are piled to b page sheets. Y foldedand through which works the folding Figure 1 is a side elevation; Fig. 2, a verblade F, the said table being a little vlonge tiral section taken transversely to Fig. 1 in than the said cylinder. Between the 0011001 the line 2 2 thereon; Fig. 3, a section taken ing-cylinder and the table is the transfer-cy' inder' T, furnished with, grippers t t i and serving to pile upon the table E one upon another every two successive collections of sheets made by the cylinder D and taken therefrom by said cylinder T. The shaft T of the transfer-cylinder is so arranged in suitable hearings in the framing as to bring the said cylinder partly under the collecting-cylinder and almost in contact therewithand at some disianceabove the table and nearer to one side than the other of the latter. Under the table are the folding-rollers G, running in suitable hearings in the framing, and under'lhe i'olding-rollers is a rotary slitt er for slittinp the folded collections of sheets crosswise of their fold-into signatures, the said slitter-consisiin-g of pairs of shearing-disks it, carried by two shafts H, running in suitable bearings in the framing. There are three pairs of such dislrs'in the present example for cutting the sheets into fours. At a suitable distance below this slitter is an intermittentlymoving endless carrier consisting of tapes 1,

running on Wheels I", carried by shafts I 1*,-

running in bearings in brackets l on the training. This carrier is of a Width equal, or

approximately'so, to the length of the table E.

Between the cutter and the collecting-c31- inder D are stationary guides 15 for directing the end of the web and the tail ends of the sheets out therefrom to said cylinder. in front er the collecting-cylinder D, between saidguides l and the transfer-cylinder T, are rollers k for holding to said cylinder D the front edges and adjacent parts of the Web a and the sheets taken by the grippers of said cylinder ID and for preventing the tail ends f the so-taken sheets from dropping to the cylinder 1 nniil the front ends of the collectio'ns have been taken by the grippers of the latter cylinder, the said rollers it being fast on arotery shaft K, running in hearings in the framing. At the hack of said guides are rollers 17 for holding the first sheet of every collection of two which is taken by either set of grippers 'e e to the cylinder in proper register, While the same set of grippers are open to take ihesecond sheet.

There are twbeetsof cutting-blades on the cutter-carriers and two sets of grippers e e on the collect-iugcyliniler. 'The shafts of said carriers and that ofthe cylinder are geared together to maize the same number of revolutions, and therefore two sheets are cut by every revolution of the cutter and two taken by the collectingcylinder during each revolution. The circumference of the collectingcylinder is a little greater thauthe circle circumscribed by the edges'of the cutting-blades in order that there may he a suiiicient space .between succeeding sheets taken on the cylthis liability of the sheets to remain upon vit is'obviated or at least greatly reduced.

The circumference of the transfer-cylinder and the number of grippers thereon must bear certain proportions to the circumference of,

and number of grippers on the collecting-cylinder, as the grippers on both have to be at corresponding distances apart, and the surface velocity of the two must correspond. In the example represented the transfer-cylinder T is of a circufifer'ence one and a half times that of the collecting-cylinder and has three sets of grippers, and the said cylinder 'I is geared with the collecting-cylinder to make two revolutions for every three of the latter. The several grippers have on their shafts e and t, respectively, outside-of one end of their respective cylinder, levers 21, Fig. 6, through which the grippers receivetheir opening and closing movements, the closing being efit'ected by springs 26, applied to one end of each of said levers inn Well-known manner not necessary to be here described, and the other end ofeach of said levers being furnished with a frictiomroll'er 20, which as the cylinder ro-. tates runs against one of a system of cams located outside the cylinder. These cams are shown in Figfinfi and 6 and arepartly visible in. Fig. 7. The cam e for opening the grippers c c of the collecting-cylinder for the reception of the sheets and the cam't foropening the grippers t 15 6 of the transfer-cylinder vfor the deposit on the table E of successive collections of two sheets taken from the collecting oylinder are stationary on the framing Ainoperative position,astheseverelgrippers are openedJor those two purposes every time they pass their respective cam; but the cam e for opening the collecting-cylinder grippers to release the successive collections of sheets therefrom and the .cam i for opening the transfer-cylinder grippers for the reception of every so-released collection have to be in their operative positions for opening their respective grippers for the transfer of the sheets from one cylinderto the other every other time only that the grippers pass the said cams e i and have to be kept out of said operative 'position during the intervening times of the The said cams e and grippers passing them. i aretherefore carried, respectively, each by one of two levers c t, which work on fixed fulcruins 15 of the framing A, the lovers e t beingrespectively operated upon through rods e 1, by cams. e t on a rotary shaft R, running in fixed hearings on the framing, the

said sha'ft tt eltlng one revolution for every two of the coll-ecti'ng cylinder. The relative and successiye operations of the grippers produced by the several cams will be hereinafter more fully described.

Behind and near the transfer-cylinder T and below the collecting-cylinder there is supported on the framing A a stationary bar 71, which is parallel with the cylinders and on which are a series of curved guard-fingers i, facing the transfer-cylinder to prevent the flying away therefrom and over the foldingblade of the tail ends of the collected couples of sheets which have been taken from the collecting-cylinder by the transfer-cylinder and are being carried by the latter to the table E to be piled thereon for folding. Immediately below the slitter and parallel with the shafts thereof there is supported in the framing A a stationary guide-bar L, on which are a series of guide-lingers Z, which project upward between the shafts H and between their disks h and which have an inclination downward under one of said shafts and toward a series of stationary stop-fingers m, which are upright immediately above that part of the carrier I on which the folded and cut signatures are to be-received, the said fingers m being carried by a stationary bar M, which is supported in the framing.

Attached to the front edgeof the table there are fixed sheet-stops g, against which the sheets so piled on said table are jogged to register by joggers j, Fig. 3, at the back of the table. These joggers are carried by a rock-shaft j, working in fixedbearings below.

the table and receiving necessary motion from an eccentric cam 7' on the shaft of one of the folding-rollers G, the said cam acting on an arm j of said rock-shaft to throw the joggers back from the table, and a spring j, applied between the said arm 9' and a fixed stop 7' on the framing, serving to throw them forward toward the table.

The folding-blade F is affixed to a barf, carried by the arms of a rock-shaftf, which is supported in fixed bearings in the framing, and it may be actuated and controlled by any suitable cam or system of cams in such manner that-it remains stationary when raised to its highest position, (shown in dotted outline in Fig. 3,) while two couples of sheets which have been collected by the. cylinder D are successively deposited in a pile of four sheets on the table E by the transfer-cylinder and that after the two couples have been so deposited and before another couple shall have been so deposited it will. strike the pile and force the sheets throughthe slot in the table,

thereby commencing an inset fold, which is to be completed by the folding-rollers G, and will returnto its highest position orhigh enough not to interfere with the next deposit on the table. The particular systemof cams O P Q and the mechanism actuated thereby for producing this operation of the folder not constituting any part of the present invention will V V with the cam-shaft.

only be here described sufficiently to prevent their confusion in the drawings with other parts-of the machinery. The cam O operates through a lever 30 and a connecting-rod 33 on an arm 27 of the rock-shaft f, and the cam Q operates through a lever 44 and connecting-rod 47 upon an arm 29 of said rockshaft.

The delivery-carrier I derives its motion from an eccentric cam 1 Figs. 3, 8, and 10, on the rotary shaft R, the said cam acting on a roller n on a pawl-lever n, which is fitted to oscillate on the said shaftR and which carries a pawl 01, working in a ratchetwh'eel 71 fast on the said shaft.

The driving of the shafts of the rotary cutter C c, collecting-cylinder D, transfer-cylinder T, folding-rollers G, and rotary slitter H h and thedriving of the cam-shaft R at the proper relative speeds may be effected in any suitable manner by properly-proportioned gearing. Let it be supposed that the one of the cutter-shafts bis the driver for all the rest and that it is driven by any suitable gearing from a rotary printing-machine to which this cutting and folding machinery is an appurtenance. A gearp, Figs. 2 and 5, on said shaft b gears with and drives the collectingcylinder through a loose gear qfon a stud g on the framing, said gear q gearing with said gearp and with a gear 1' on hlshaft of the collecting-cylinder. Thetransfer-cylinderis driven from the collecting-cylinder by a gear 8, Figs. 1 and 2, on the latter and a gear t on the former. The shafts of the foldingrollers G, which are geared together, are driven from the gear t on the transfer-cylinder shaft through a stud-gear u, Figs. 1 and 2,-

which gears with a gearo on one of the foldingroller shafts. The slitter-shafts, which are geared together, are driven from one of the folding-roller shafts through a stud-gear w.

The cam-shaft R. is driven from the shaft T of the transfer-cylinder through a side shaft S, running in brackets-S on the outside of the framing, said shaft S gearing by mitergearsU with said shaft '1" and by bevel-gears The-shafts K and 16 of the rollers k and-17 are driven directly from the gear 8, before mentioned, on'the collecting-cylinder through gears 00 and y, Fig. 1, on said shafts K and 16.

The several parts of the machinery itself having now been described, the successive operations from the cutting from the web of the sheets, such as are shown in Fig. 11, to the production of the signatures, such as are shown in Fig. 12, will now be briefly explained.

Four sheets cut successively from the web are taken, the first and the third ones by one set of grippers e or e of the collecting-cylinder to form one couple, and the second and fourth ones by the other set of grippers of two so-collected couples are taken from each of said sets of grippers in succession by one after another of the sets of grippers 15 t t of the transfeccylinder, the relative positions of the several sets of grippers e e and t. t t

on their respective cylinders and their remake the traust'er'from one cylinder to theother and that the grippers of the transfercylinder are closed again before the closure of those of the collecting-cylinder. As each collection of a couple of sheets collected on the transfer-cylinderisbrought byaset ofg'rippers of said cylinder to a proper position over the table the said grippers are opened and the collection is deposited on the table and jogged to register thereon. 'lwosuch deposits having been successively made upon the folding table while the folding-blade remains raised to its highest position, (represented in dotted outline in lfig. 3,) the said blade descends, striking the sheets on the center line50, Fig. 11, which is parallel with the edges formed by cntting-from the web, and carries the set oifonr, sheets through the slot in the table and between the folding-rollers, by which by which they are so deflected that they strike the stops m and are socaused to be deposited, lying down, npon'the endless carrier 1 in sets of four sixteen page open-edged signatures. :The' carrier making a very short movement after every deposit carries away i the successive deposits, each overlapping. the
